TRANSMISSON BAND.

Application filed March 26, 1921.

,To all fwhom it may concern.'

Be it known that l, VVAmnn J. BnowNrmLo, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in T ransmission Bands, of which the following is a specication, reference being had to the accompanying drawings.

This invention relates to improvements in transmission bands, and more particularly to the manner of mounting the ears of the transmission band upon a band.

An important object of the invention is to provide a readily disengageable mounting for one of the ears of the transmission band. ln many cars the ears on the transmission bands prevent the removal of the bands for renewal of their gripping surfaces by reason of the fact that not sulicient play is provided to permit of removal of the bands while the ears are attached thereto.

ln accordance with my invention one of the ears of the transmission bands is made removable so as t0 permit withdrawal of the bands without removal of thetransmission or any portion thereof.

Other objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings wherein for the purpose of illustration are shown preferred embodiments of my invention and wherein like reference characters designato like parts throughout:

Figure 1 is a fragmentary perspective of the adjacent ends of a transmission bearing constructed in accordance with my invention;

Figure 2 is a plan view removable ear;

Figure 3 is a plan view of a second form, and

Figure 4 is a longitudinal sectional view showing a removable ear mounted upon a transmission band and in position for removal in solid lines.

Referring now more particularly to the drawings, the numeral l() indicates a transmission band'l provided at one end with an engaging ear 11 which is permanently secured thereto. The opposite end of the band has secured thereto a stop or shoulder member 12 provided-in its face with a slot 13 for a purpose present-ly to appear. Secured to the band at a point spaced from the stop or of one form of Specification of Letters Patent.
